Constructor Details

BooleanArray

public BooleanArray()

Create a new default array with size 512 items

BooleanArray

public BooleanArray(int initialSize)

Create an array with the given initial size

Parameters:

initialSize - The size to start with

Method Details

size

public int size()

Get the count of the number of items in the array.

Returns:

The number of items in the array

clear

public void clear()

Clear the array so that it contains no values

add

public void add(boolean newBoolean)

Add a new value to the array. Will resize the array if needed to accommodate new values.

Parameters:

newBoolean - the value to be added

add

public void add(boolean[] values)

Add an array of values in bulk to the array. The array should not be null.

Parameters:

values - The values to be added

get

public boolean get(int index)

Get the value at the given index.

Parameters:

index - The position to get values from

Returns:

The value at that index

Throws:

IndexOutOfBoundsException - The index was not legal

set

public void set(int index,
 boolean value)

Set the value at the given index. If the index is out of the range of the current items, it will generate an index exception.

Parameters:

index - The position to get values from

value - The new value to set

Throws:

IndexOutOfBoundsException - The index was not legal

remove

public boolean remove(int index)

Remove the value at the given index.

Parameters:

index - The position to remove the value from

Returns:

The value at that index

Throws:

IndexOutOfBoundsException - The index was not legal

toArray

public boolean[] toArray()

Turn the values of this array into a real array. Returns an array with the exact number of items in it. This is a separate copy of the internal array.

Returns:

The array of values

toArray

public boolean[] toArray(boolean[] values)

Turn the values of this array into a real array by copying them into the given array if possible. If the array is big enough then it will copy the values straight in. If not, it will ignore that array and create it's own copy and return that. If the passed array is used, the return value will be a reference to the passed array, otherwise it will be the new copy.

Parameters:

values - The array to copy values to

Returns:

The array of values
